Abstract

In this paper,the cyclic voltammetric and spectroelectrochemical behaviors of μ _oxamido Copper(Ⅱ) Binuclear Complex (deCu) in PBS were studied.Cyclic voltammograms of this complex in PBS(pH=9)exhibited two reductive peaks( E pc1 =-0.25 V, E pc2 =-0.50 V)at hanging mercury drop electrode(HMDE),peaks at -0.50 V and -0.25 V corresponded to the reduction of ligand and copper(Ⅱ)_complex, respectively.The spectroelectrochimical experiments showed that there was a new absorption band at 440 nm,and the absorption peaks at 270 nm,280 nm red shifted to 300 nm,310 nm under potential of -0.75 V.It was meant that the Cu(Ⅱ) turned into low valent copper,simultaneously,a new large coupling system occurred.The redox reaction of film was measured two electrons and two protons transition process by cyclic voltammetry.Especially the deCu modified electrode showed a good catalytic ability to cysteine,L_Tryptophan as well as L_Proline.
